[FFmpeg-user] [lavc rc] Error: 2pass curve failed to converge

[Tom]

Hi,

I'm trying to convert a series of jpegs to a movie, and I get an error
(log below).
I've done this earlier, without issues, for other jpegs, but for this
particular set, i get the error. I don't know how.

I'm using the latest version of ffmpeg (i built it last week from git
sources), on ubuntu 8.04.

My images can be downloaded on:
http://www.compulated.info/ffmpegtest_images.zip (6 MB)

The error I get is (see pass 2):

mpeg -vcodec mpeg2video -an -pass 1 -passlogfile pass.txt -y
video_14.mpg 2>&1

Can anyone help? I've searched google, but all errors of this kind
were solved in 2006-2007 apparently, so it doesn't seem to be valid
for me...

Cheers,
